Have a loot at there:

You have to register a BroadcastReciever in your Manifest (like your
outgoing one) with the intent filter android.intent.action.PHONE_STATE
and you need the Permission READ_PHONE_STATE.
If you check for the state CALL_STATE_RINGING, then you know there is
a incoming call. Then you can start your app. You can start your
activity or service.
I'm working on a app using this as well, but at the moment I'm at work
and don't have the source in front of me, to give you detailed
example. Maybe you can find out with the help i gave you here, if not
i can post some example later the day when I'm at home.
